We are praying that you find him. Be sure to alert all of the vets in the area as well as the humane society so that they can watch for him. Whoever took him might take him to the vet. Also, might want to consider asking all of the local stores that allow pets to come in to put up a poster as well. They might go in and take him with them and they can call the police or something. Is it possible to file a police report? That way if someone did call the police they can detain them? Not sure how that would work.
At any rate, I will forward the alert to everyone I know. Keep your chin up!
